Seriously though RSS has never died and tonnes of us still use it despite the efforts of close-walled companies like Facebook and Twitter disabling it on their services. It is the only way I like to consume my news, particularly tech news, as there are just too many sources to do it any other way.

There are some services/clients that try to do what you describe and filter your feeds to emphasise keywords, authors etc.. that you are interested in. They are generally pretty immature though and I would welcome some better systems for this, as long as it is transparent what they are including and excluding.
